Some rough notes:
You do NOT NEED the following:
Sound person, AD, clapper, more than one vehicle bigger than a small van, makeup, (most of the time) a storyboard artist, craft services (with a tiny crew food is taken care of by your multi skilled, multi tasking super assistant.)
Neither do you need walkie talkies, or a locations manager. Or a colorist, a title person, a composer, production manager, production designer, sound designer, and lots more. You don't need them!!!
(You do all or almost all post production yourself.)
This is disruptive. To find out more watch the full movie. What you will learn will save you thousands of dollars, and many many hours of time. You will learn a new filmmaking philosophy and a new way of thinking, which are essential to making money with micro budget movies.
